Diocese of Pontus

The Diocese of Pontus was a regional administrative district of the Roman Empire which was created during Diocletian's reforms during his reign from 293-305 AD, covering central and northern Asia Minor. Following the Edict of Milan in 313 AD, the Christian Church was legalized, and it created dioceses in every Roman province; these existed until the late 5th century. The diocese was one of the dioceses which adopted Orthodox Christianity under the Byzantine Empire following the First Council of Nicaea in 325 AD.
